507288 ÷ 50 
The aim is to understand the frequency of 50 in 507288.

Let's proceed to step 1:
The number 50 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 50

Let's proceed to step 2:
When dividing 50 by 50, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 50 from 50, we get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 50

Step 3:
When dividing 7 by 50, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 7, we get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 50

On to step 4:
The number 50 fits into 72 1 times, leaving a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
If we subtract 50 from 72, we get 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 50

On to step 5:
50 goes into 228 4 times with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 1014.0
If we take 200 away from 228, we end up with 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 50

On to step 6:
50 goes into 288 5 times with a remainder of 38.
Write down 5 as next digit of the result. 
Result so far: 10145.0
If we take 250 away from 288, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 7:
The number 50 fits into 380 7 times, leaving a remainder of 30.
The number 7 becomes the next digit in our result. 
Result so far: 10145.7
Subtracting 350 from 380 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
300 divided by 50 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 10145.76
Subtract 300 from 300 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10145.76
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
50 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10145.76
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 10145.76, with a leftover of 0.0.
